This is just a general interest question. My friend has got two 12 week old male kittens. They are adorable creatures, but always fighting, springing, hunting and so on. I know this is normal kitten behaviour, but these two are completely wired.
In other's experience, are male kittens more boisterous than female kittens (a bit like boys tend to be in comparison to girls) and how can my friend stop them from becoming unmanageable before they are old enough be neutered?
